What is a SerDes circuit?
A SerDes (Serializer/Deserializer) is an integrated circuit or device in use in high-speed communications that converts between serial data and parallel interfaces in either direction.
What is SerDes transceiver?
A SerDes or serializer/deserializer is an integrated circuit (IC or chip) transceiver that converts parallel data to serial data and vice-versa. The transmitter section is a serial-to-parallel converter, and the receiver section is a parallel-to-serial converter.
Is SerDes bidirectional?
SerDes provides real-time bidirectional control for driver-assist cameras. National Semiconductor unveiled its FPD-Link III family of automotive-grade serializer and deserializer (SerDes) chipsets featuring the industry’s first real-time, bidirectional control channel for driver-assist video cameras.
What is PMA in SerDes?
SERDES Architecture The SERDES is primarily comprised of the Physical Medium Dependent (PMD) sublayer, the Physical Media Attachment (PMA) sublayer and the Physical Coding Sublayer (PCS). The PMD is the electrical block responsible for the serial signal transmission.
Is SerDes analog?
Typically, the SerDes are analog based designs, employing phase-locked loops (PLLs) or delay locked loops (DLLs) (Figure 1 ).
What is a Serializer and deserializer?
A serializer/deserializer (SerDes) is an integrated circuit or device used in high-speed communications for converting between serial data and parallel interfaces in both directions.
What is PMA in VLSI?
The Physical Media Attachment (PMA) Layer includes high-speed analog and digital circuitry for PCI Express signaling, also includes differential drivers and receivers for on lane in a link. Serial transmission takes place over the link and there’s a 10-bit parallel implementation-specific interface between PCS and PMA.
What is reconciliation sublayer?
Reconcilliation layer in the Fast Ethernet layer model. Here, the reconciliation sublayer takes over the logical interface between the MAC layer with the media access method and the Media Independent Interface and converts the primitives from the MAC layer and the Physical Layer Signaling( PLS) into MII signals.
Is SerDes mixed signal?
SerDes is mixed-signal. With digital designs you can just move the same design from 7nm to 5nm by resynthesizing it.
Is marshalling the same as serialization?
Marshalling is like serialization, except marshalling also records codebases. Marshalling is different from serialization in that marshalling treats remote objects specially. Any object whose methods can be invoked [on an object in another Java virtual machine] must implement the java.
What is PCS and PMA?
The physical coding sublayer (PCS) is a networking protocol sublayer in the Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet standards. It resides at the top of the physical layer (PHY), and provides an interface between the Physical Medium Attachment (PMA) sublayer and the media-independent interface (MII).
What is a PHY in VLSI?
A PHY, an abbreviation for “physical layer”, is an electronic circuit, usually implemented as an integrated circuit, required to implement physical layer functions of the OSI model in a network interface controller.
What is SerDes IP?
SERDES s stands for Serializer/Deserializer. It is essentially an IP block that can convert parallel data into serial data. As suggested by the name, this device has two functional components that serve to convert data from parallel interfaces in each direction.
Is Xilinx’s design/code/information copyright free?
Xilinx is providing this design, code, or information “as is.” By providing the design, code, or information as one possible implementation of this feature, application, or standard, Xilinx makes no representation that this implementation is free from any claims of infringement.
Why choose Xilinx?
In addition, Xilinx offers an extensive network of “ecosystem” partners (EDA, reference design, IP, design services, etc.) to guarantee interoperability and access to the latest technology, techniques, and design tools. The world isembracing serial technology.
How to speed up Xilinx SerDes?
To push the speed or avoid using global clocking, some extra work might be required. But, with fewer pins, more speed, and all the other benefits, an integrated SERDES is a better solution. We will use the MGT links again and encourage Xilinx to give us both faster and slower SERDES in the future.
What is source synchronous in Xilinx?
HIGH-SPEEDSERIALI/O MADESIMPLE• 194 • Xilinx PRELIMINARYINFORMATION Source Synchronous: Communication between two ICs where the transmitting IC generates a clock that accompanies the data. The receiving IC uses this forwarded clock for data reception.
